Sidewinder is the world’s first Xilinx® Zynq® UltraScale+™ ZU19EG Storage Accelerator PCIe card. But don’t let the ‘Storage Accelerator’ title limit you, Sidewinder’s ZU19EG is also well suited for anything NVMe, NVMe Over Fabrics (NVMEoF, NVMF) workload acceleration, high-frequency trading, and general Zynq US+ development and experimentation.

Zynq US+ XCZU19EG-2FFVC1760 FPGA
A huge Zynq UltraScale+ ZU19EG device is housed under the cooling system.
The Zynq US+ features:
- Quad-Core ARM Cortex-A53 Application Processing Unit
- Dual-Core ARM Cortex-R5 Real Time Processing Unit
- ARM Mali™-400 MP2 Graphics Processing Unit (GPU)
- Lots of extremely high-speed peripherals
PCIe Host Connector
PCIe endpoint supporting Gen4 x8 or Gen3 x16.
PCIe Expansion Port
A PCIe x8 Host Port supporting expansion SSDs or other PCIe add-in cards (you will recognize this port as a x16, but it’s wired only as a x8).
2x 100G QSFP+ Cages
Each with 25Gbps x4 connectivity to ZU19EG.
Sidewinder includes two M.2 sockets to support on board NVMe Solid State Drives (SSD). Add lots of onboard storage! One of the M.2 ports can optionally be used as a boot device for the card. Drives not included.
Two (2) 8643 connectors at the back end of the card enable connection to off-board SSDs (typically via an 8643 to U.2 cable).
10/100/1000BaseT LAN port
The GigE capable LAN port on Sidewinder is connected directly to the Zynq UltraScale+’s PS. Use this port for management, status, debug, or data plane activities.
Sidewinder is outfitted with two DDR4* PC4-2400 memory modules. One module is connected to the Zynq UltraScale+ PS while the other is connected to the PL (the internal FPGA fabric). With this memory the ARM processors can run extensive operating systems and execute other sophisticated instruction sets. In addition, by dedicating memory to the PL (the internal FPGA fabric), the algorithms that are being accelerated with the FPGA have plenty of buffer in which to operate. The SO-DIMMs are each 16GB, 72-bit with ECC, with a dual rank structure.
*As per Xilinx specification, with this structure of memory, maximum achievable PS rate = 1866MT/s, and PL rate = 2166MT/s.
A micro-USB connector (device only) backed by a USB-to-UART chip, provides access to two (2) serial port connections on the Zynq US+ PS. Intended for use during development.
uSD Card Slot
Carefully hidden away on the back of Sidewinder is a uSD slot. This slot is intended for program storage.
ATX Input Power Connector
When “in-system” the ATX power connector input, in conjunction with the PCIe edge connector, work in tandem to power Sidewinder. The same is true for desktop operation – that is, the “PCIe Power and Loopback Adapter” is required as well as the ATX power connector input.
Development. Loop it.
The Sidewinder Loopback Kit is an invaluable tool during your development. Purchase separately from Sidewinder.
Included in the loopback kit:
PCIe Power and Loopback Adapter
This simple, yet invaluable card allows you to not only power Sidewinder on a desktop (ATX power also required), but it also loops back the high-speed PCIe differential pairs to assist in development and debug. Card ships with banana jacks (not shown below). An onboard oscillator provides the PCIe clock.
PCIe Expansion Port Loopback
Speed up your development by looping back the PCIe expansion port.
Want to confirm that your signals are correctly reaching the M.2 slots? Plug in an M.2 loopback PCB, and using Xilinx’s IBERT, check to see if you’re ready to access a real M.2 SSD. As there are two M.2 slots on Sidewinder, the loopback kit includes two M.2 loopback cards.
8643 Loopback Cable
Test out the 8643 functionality by looping one 8643 connector back into the other.
A fully provisioned loopback system.
